Palpation of Major Arteries in the Head and Neck

Introduction

Palpation of arteries in the head and neck is an essential clinical skill for assessing vascular health. Among these, the superficial temporal artery is easily accessible and provides valuable diagnostic information.

Anatomy of the Superficial Temporal Artery

The superficial temporal artery is a terminal branch of the external carotid artery. It supplies blood to the scalp and face and can be palpated anterior to the tragus.

Palpation Technique

• Positioning: Ask the patient to relax in a seated or supine position.
• Locating the artery: Identify the tragus of the ear and palpate anteriorly.
• Using fingertips: Place the index and middle fingers gently over the artery.
• Assess pulse characteristics: Evaluate rate, rhythm, amplitude, and contour.
• Clinical significance: Abnormalities may indicate temporal arteritis, hypertension, or vascular insufficiency.

Clinical Relevance

Palpation of the superficial temporal artery aids in diagnosing vascular conditions. Temporal arteritis, characterized by inflammation of the artery, may present with tenderness and absent pulse.

Conclusion

Accurate palpation of the superficial temporal artery is crucial for vascular assessment. Clinicians must master this technique to detect abnormalities and optimize patient care.
